Mixed vaccines gives better immunity – UK study

A UK study, called Com-COV2, found that Pfizer or AstraZeneca Covid19 first-dose vaccines elicited a stronger immune response when paired with Moderna nine weeks later.


The immunity generated was found to be higher than that of two AstraZeneca doses, according to Oxford professor Matthew Snape, who led the trial.


This comes as good news for low- to middle-income countries who are still administering the first two doses and may be experiencing shortage of various brands of vaccines.


“We’re showing…you don’t have to stick rigidly to receiving the same vaccine for a second dose…and that if the program will be delivered more quickly by using multiple vaccines, then it is okay to do so,” said Snape.


Their study revealed that a Pfizer dose followed by Moderna produced an immune response stronger than that of two doses of Pfizer. Meanwhile, Pfizer paired with Novavax produced higher antibodies than do two doses of AstraZeneca, but lower than two doses of Pfizer.


In addition, the trial demonstrated that a first dose of AstraZeneca followed by any other brand of vaccine elicited a particularly strong response.


While not much data has been gleaned regarding mixing and matching vaccines, many nations have gone ahead and done so. The rising number of cases and the emergence of new variants such as Omicron has added to the pressure.
